Definitions
- the present invention relates to a mobile Internet call service, and more specifically, to a device and method for providing a mobile Internet call service that can minimize a waiting time for an actual call by reducing preprocessing for a mobile Internet (mobile voice over Internet protocol, hereinafter referred to as an mVoIP) call, that is, a time taken for an information acquisition process necessary for a call connection in call originating for a mobile Internet call.
- mVoIP mobile voice over Internet protocol
- This mVoIP is technology that can use an Internet phone using a terminal through Wi-Fi (a wireless LAN) and wireless mobile Internet such as a 3G network.
- a transmission rate of the mVoIP is lower than that of a VoIP.
- Internet-enabled terminals such as a smartphone become popular, the number of mVoIP subscribers has rapidly increased. It is no exaggeration to say that all users of Internet-enabled terminals are potential mVoIP users.
- NAT network address translation
- SIP session initiation protocol
- the invention provides a device and method for providing a mobile Internet call service that can provide a rapid response and improve user satisfaction by significantly reducing a call waiting time when an mVoIP call attempt is made.
- a device for providing a mobile Internet call service as further defined in claim 1.
- a method of providing a mobile Internet call service as further defined in claim 5.
- a computer readable recording medium as further defined in claim 7.
- a call waiting time for the mVoIP call when a call is an initial call after power of a terminal is turned on or using the main call number, information for a call connection is acquired in advance and the light weight session is maintained. When the mVoIP call is made later, the light weight session is used to make a direct P2P call. Therefore, it is possible to reduce a call connection time. As a result, when the mVoIP call attempt is made, a call waiting time is significantly reduced and thus it is possible to provide a rapid response and improve user satisfaction.
- server system access for NAT information acquisition and SIP signaling is unnecessary.
- the information necessary for the call connection refers to port information such as NAP information.
- the information necessary for the call connection is acquired in advance and the acquired information is used to attempt the direct call connection.
- This state refers to a state in which a light weight session is maintained.
- the term "light weight session” may be used as a term to indicate a state in which a direct connection is not made with a partner terminal but information necessary for a call connection is acquired, and thus a direct call connection can be performed using the acquired information.
- an NAT information acquisition process and an SIP signaling process are performed through an Internet network 120 and an NAT & SIP signaling system 130 (S100 to S106). Then, the calling terminal 100 attempts a P2P connection with the incoming terminal 110 using the acquired NAT information (S107).
- an operation of S107 is performed after operations of S100 to S106 are performed.
- operations of S100 to S106 are performed as described in FIG. 1 only when a call is an initial call after power of a terminal is turned on or using a main call number. NAT information acquired through these operations is stored and the light weight session is maintained. In this case, since it is difficult to maintain the light weight session for many call subjects, the light weight session is maintained for only the main call number that is predetermined by a user. In addition, when there are many predetermined main call numbers, it is difficult to maintain the light weight session for all main call numbers.
- an algorithm for designating a priority of the main call numbers and a policy for increasing a hit rate in the terminal may be used.
- a configuration between a calling terminal and an incoming terminal in an mVoIP call service providing system according to an embodiment of the invention will be described with reference to FIG. 2 .
- an application capable of supporting an mVoIP call service is downloaded and stored in terminals 200 and 210 according to the invention.
- the light weight session is previously set for the main call number and is maintained as described in FIG. 1 . Then, when the calling terminal 200 requests an mVoIP call, the NAT information acquisition process and the SIP signaling process (S100 to S106) in FIG. 1 are not performed. As illustrated in FIG. 2 , a direct P2P connection attempt is made. In this way, it is possible to reduce a call waiting time.
- the terminal 200 may include a control unit 300, a communication unit 302, an input unit 304, an output unit 306, and a storage unit 308.
- the control unit 300 controls overall operations of the terminal 200 and operations related to application driving for an mVoIP call service.
- the control unit 300 has different control operations according to two embodiments. First, control operations for the mVoIP call service according to a first embodiment will be described.
- the control unit 300 performs a signaling process of sending a signal for acquiring NAT information of the main call numbers that are predetermined by the user when power of the terminal 200 is initially turned on.
- signaling may include an SIP, an XMPP, or a third party protocol.
- the control unit 300 checks whether NAT information of the incoming terminal 210 is present in the NAT & SIP signaling system 130 having NAT information of a plurality of terminals. When corresponding NAT information may not be transmitted to the terminal 200, the control unit 300 sends signaling of NAT information to the incoming terminal 210 and the incoming terminal 210 transmits only a response signal therefor.
- the control unit 300 stores the acquired NAT information of predetermined main call numbers, that is, information for a call connection, in the storage unit 308.
- the control unit 300 performs control such that pre-stored NAT information is used to attempt a P2P call connection to the incoming terminal according to whether a calling number is a number stored as the main call number.
- the control unit 300 determines whether a calling number is an initial call request.
- the control unit 300 performs control such that the NAT information acquisition and the SIP signaling process are performed, the acquired NAT information is used to attempt a P2P call connection to the incoming terminal, and the acquired NAT information is not deleted but stored in the storage unit 308, and may be used for call originating for an mVoIP call that is generated later.
- the control unit 300 performs control such that stored NAT information is used to attempt a P2P call connection to the incoming terminal.
- a state in which the NAT information is stored in advance and a session for a call connection is maintained in order to reduce a waiting time for a call connection when an mVoIP call service is provided is referred to as a light weight session state.
- Such a light weight session may be initialized when power of the terminal is turned on or off.
- the communication unit 302 transmits and receives data for the mVoIP call service via a communication network.
- This communication unit 302 may transmit and receive data through various communication methods in addition to wired and wireless methods.
- the communication unit 302 may transmit and receive data using at least one communication method.
- the communication unit 302 may include a plurality of communication modules that transmit and receive data according to different communication methods.
- the input unit 304 may generate a user input signal corresponding a user request or information in response to the user's manipulation.
- the input unit 304 may be implemented by currently available input devices or input devices to be commercialized. Examples of the input unit may include general input devices such as a keyboard, a mouse, a joystick, a touch screen, and a touch pad, and gesture input devices in which the user's motion is detected and a specific input signal is generated.
- the output unit 306 enables an operation result or a state of the terminal 200 to be recognized by the user.
- Examples of the output unit may include a display unit configured to visually output the result and state through a screen or a speaker configured to output audible sound.
- a screen related to the mVoIP call service that is operated in the terminal 200 may be displayed.
- the storage unit 308 stores information necessary for operating the terminal 200, and in particular, stores an application that provides the mVoIP call service according to the invention and a main call number list 310.
- the main call number list is a list in which subjects who are frequently contacted by the user through the mVoIP call are pre-set by the user and stored.
- the storage unit 308 may include a hard disk, a floppy disk, magnetic media such as a magnetic tape, optical media such as a compact disc read only memory (CD-ROM) and a digital video disc (DVD), magneto-optical media such as a floptical disk, a ROM, a random access memory (RAM), and a flash memory.
- a method of providing an mVoIP call service in the terminal 200 configured as described above will be described in detail with reference to FIGS. 4 to 6 .
- FIGS. 4 and 5 are flowcharts illustrating an initial setting and call connection process in a terminal for providing an Internet call service according to the first embodiment of the invention.
- FIG. 6 is a flowchart illustrating a call connection process in a terminal for providing an Internet call service according to the second embodiment of the invention. It is assumed that the main call number list is set by the user and stored in advance when the first and second embodiments are described.
- the control unit 300 of the terminal 200 when power is turned on, sends a signal that can obtain NAT information of the main call numbers preset by the user (S400 and S402). That is, when power of the terminal 200 is initially turned on, the control unit 300 performs a signaling process for acquiring NAT information of the main call numbers preset by the user.
- the signaling may include an SIP, an XMPP, or a third party protocol.
- control unit 300 checks whether NAT information of the incoming terminal 210 is present in the NAT & SIP signaling system 130 having NAT information of a plurality of terminals. When corresponding NAT information may not be transmitted to the terminal 200, the control unit 300 sends signaling of NAT information to the incoming terminal 210 and the incoming terminal 210 transmits only a response signal therefor.
- the control unit 300 performs the NAT information acquisition and the SIP signaling process through the communication unit 302 (S404 and S406).
